Workshop technician personal year-end summary

Since I came to the xx park in July XX, I have been working for more than a year now. During the year, I worked in the project department, responsible for on-site management and technical guidance of electrical construction. With my own efforts and leadership, I was promoted from an ordinary electrical supervisor to a concurrent electric workshop. Technician position. During this period, in addition to being responsible for the electrical construction supervision of the workshops belonging to the North and South factories, I also assumed the duties of the technicians in the electrical workshop. Although the workload was much heavier than before, it gave me a comprehensive understanding of the company's entire electrical system, strengthened my knowledge of the company's electrical system, and improved my independence from some systems. The ability to analyze and deal with problems has laid a good foundation for me to further work in electrical technology.
Below I summarize the work of the workshop technicians in XX.
1. My understanding and attitude towards the work of the electrician technicians After I was appointed as the technician of the electric meter workshop, I began to gradually enter this role. Although I used to be an electrical equipmentman at xx Pharmaceutical Co., Ltd., I have a deep understanding and mastery of high and low voltage electrical technology and equipment. However, since I have been working on the new construction site, I feel that the pressure to be a qualified electrician is increasing. There are mainly the following reasons: First, the company's electrical equipment is huge; second, there are many types of electrical equipment, involving high and low voltage transmission, power distribution, power transmission and electrical maintenance; third, the mixing of old and new equipment increases the failure of electrical equipment. The odds and difficulty of troubleshooting; Fourth, the new 110kva substation, this is a new thing that I have not touched before; Fifth, I have not worked on the instrument for three or four years, I have to relearn the previously missing knowledge.
In the face of this pressure, I feel that my responsibility is significant. It is my focus to provide technical support for the normal and stable operation of the company's electrical equipment and to deal with sudden failures. I believe that I have the ability to do this work well. The greater the pressure, the greater the motivation. In the early days of electrical technicians, I was familiar with and familiar with the previously unfamiliar 7-aca fermentation workshop, 7-aca refining workshop, power plant and water station, 110kv substation and 10kv switchgear. Collect and use the manuals for electrical equipment that has not been touched before, and be familiar with the working principle and parameter setting, maintenance and troubleshooting methods. Discuss the problem with the manufacturer and related personnel to ensure the thoroughness of the relevant equipment.
In addition, I communicated with the maintenance team, operation group and instrument cluster of the workshop to understand the knowledge level of the existing employees and the technical problems that exist in the current work.
2. Work content of the current year 1. The daily work content, the clavulanic acid oral sterile workshop centrifuge, can not be started when the material is full. After I checked it, I found that the load was too heavy before the centrifuge was started. The power delivered by the inverter cannot overcome this torque, causing the centrifuge to fail to start. After understanding the working reason, I reset the starting torque of the inverter and put in the DC braking resistor to extend the starting time and ensure the normal use of the centrifuge.
In the boiler workshop, the 1# induced draft fan inverter always reports “overcurrent when parking”. After my analysis, it is found that the operator stops too fast when parking, and does not stop quickly when the frequency is gradually reduced. . In order to solve this problem completely, I installed a DC reactor for the inverter and set the application parameters of the DC reactor to solve this problem from a technical level. In addition, in order to ensure the normal operation of the equipment, I also explained to the operator of the boiler workshop the normal startup program and precautions.
, Clavulanic acid refining a thin film evaporator in the workshop, the pressure has been at a high level during the use process, can not guarantee the normal operation of production, after I negotiated with Yang Bo, it is recommended to use the inverter control method. The pressure of the equipment is controlled by human means to ensure the stability of production. In the end, we installed a frequency converter for 8 thin-film evaporators, and through a period of operation, we determined that the effect met the expected requirements.
3, reverse osmosis high pressure pump in the plant of Clavulanic Acid Fermentation. When the trial line is used, the inverter can't work normally. After I check it, I found that the parameters of the inverter have been changed artificially, causing conflicts in the running parameters of the inverter. In order to solve this problem, I reset the parameters to ensure the official use of the device.
In the sewage dewatering machine room centrifuge, during the operation, the current fault is reported. After the on-site inspection, I confirm that there is a problem with the motor of the inverter. After further checking the motor, it was found that the motor was short-circuited between turns. After the motor is repaired, the equipment returns to normal.
The main hot water solenoid valve in the boiler workshop, the circuit board is often broken down. I analyze that the working power supply is contaminated by the inverter and other DC electrical equipment, resulting in voltage superposition, forming a high voltage, causing breakdown of the working circuit board. Therefore, I suggest that the regulator be installed in the workshop to supply power to the instrumentation equipment separately to ensure the safe use and stable operation of the instrumentation equipment.
These are just a small part of my daily work. Such accidents often happen. When I need to deal with it, I will always come to the scene first, do my best to troubleshoot the workshop as soon as possible, and restore the normal operation of the equipment. .
Second, technical transformation, July technical transformation of the main circuit of the 304# large tank inverter control cabinet of Clavulanic acid fermentation, changed from 4# transformer load circuit to 1# transformer load circuit. Reduce the load on the 4# transformer. Before the transformation of 4# transformer, the maximum load can reach more than 4000a, which is higher than 15% of the rated current of the transformer, which seriously threatens the safe operation of the 4# transformer and leaves a major hidden danger to the normal production of the workshop. In this regard, we carried out the above transformation after the unified leadership of the workshop, the proposal, and the feasibility study. Through the transformation, the load of the 4# transformer can be maintained at 3200a in the high production stage, ensuring the safety of the equipment and achieving the expected effect of the transformation.
In August, the drum and the draft electric control loop of the boiler workshop 1-4# furnace were interlocked. The boiler workshop 1-4# furnace is the old equipment that was removed from the big medicine. There is no electrical control chain in the old drum induced electric wind. In the production, the induced draft fan stops due to sudden accidents, and the blower continues to operate, which can cause the boiler to temper, which may cause damage to equipment and personnel. In this regard, in the absence of drawings, I measured the electrical circuit of the drum and the induction motor control inverter cabinet in the boiler workshop, and finally found the way of chain control. Under the cooperation of a group of electrical maintenance, this item was completed. Renovation to achieve the purpose of transformation.
In October, the electric instrument interlocking control method of reverse osmosis in the plant of clavulanic acid fermentation was reformed. In the past, the system only protected the high pressure and high temperature, and did not stop the protection against the low pressure. This caused the high pressure pump to burn out. However, in the process of returning to the low pressure protection, the cleaning pump could not be in the low pressure state. The failure of starting the car. After communication with the workshop, I found that the original manufacturer's drawing design is flawed. After I changed the drawing, I switched to the chain line and the equipment returned to normal.
In the construction process, due to the design and the connection of new and old equipment, the circuit of some workshops is not equipped with a meter. For this reason, I installed a meter for this part of the circuit under the arrangement of the workshop. The specific installation location includes 7-aca refining the first floor of the east and third floor east; the south district canteen to send electricity to the 30-meter street lamp; the north district finished product library two refrigeration power circuit.
Third, employee training work Staff training has always been one of the key tasks of the workshop. The level of employee technology is related to the efficiency of the workshop maintenance equipment. I have also done a lot of work on this.
First of all, I have written three basic teaching plans: "Electrical Basic Training Materials", "Frequent Faults and Troubleshooting Methods for Inverters", and "Removal Methods for Common Faults in Soft Starts".
Secondly, I trained all electrical maintenance personnel, instrument maintenance personnel and electrical operators in the electric instrument workshop in June, August, September and November. The main contents of the training include electrical basic knowledge, parameter setting of the inverter, common faults and troubleshooting methods of soft start, principle of DC bridge and usage methods. And in September, all electrical maintenance personnel, instrument maintenance personnel and electrical operation personnel were assessed, and the passing rate of assessment was over 97%, reaching the expected goal of training.
IV. Parking and overhaul of 7-aca fermentation workshop in North Plant Area In the middle of July and mid-August in the North Plant, the 7-aca fermentation plant was shut down for production and maintenance. We formulated the feasibility according to the company's shutdown plan and the problems found in the daily maintenance of the electrical workshop. The electrical overhaul program and proposed a replacement spare parts application plan. After the workshop review, further improve the maintenance plan, determine the task point, work target, maintenance time, maintenance person in charge, safety precautions, maintenance quality standards and specific maintenance personnel for each maintenance work. The responsibilities of the workshop technicians to provide technical support and on-site quality spot checks were clarified, and the workshop assistant was responsible for the second sampling inspection and the quality of inspection and maintenance.
During the period, I strictly performed my duties, and I went to the on-site inspection site every day. Under the premise of providing technical support for electrical maintenance and electrical operation personnel, I will effectively control the quality of inspection and maintenance to ensure that the inspection work meets the quality standards.
After the overhaul, we summarized the maintenance work, summed up the advantages and disadvantages of this maintenance work, and promoted it to the whole workshop to provide experience for future work.
V. Collection and Arrangement of Equipment Information I paid attention to the collection of various electrical equipment materials in project management. Although the construction of most workshops has come to an end, but the construction side has fewer personnel, there are many problems in the production and improvement of the completion data, and the completion data cannot be reported to us as soon as possible. In this regard, I negotiated with the construction party. So far, the clavulanic acid fermentation workshop, the Clavulanic acid refining workshop, the completion data of the oral sterile and potassium oral two workshops have been basically improved; the 110kv substation data has been improved; the completion data of the sewage station is being improved; 7-aca fermentation , refining; power plant and water station; boiler workshop; and other completed materials are being produced.
VI. Preparation of various documents The following documents were prepared and revised during the year.
1, the daily inspection document of the electric instrument workshop "Southern District electrical maintenance inspection work specifications" "North District electrical maintenance inspection work specifications" "South District instrument maintenance inspection work specifications" "North District instrument maintenance inspection work specifications" "Electrical operation inspection work specifications 》
2, smp document "plant power supply system management program" "high voltage power distribution management program" "low voltage distribution management program"
3, sop document "Electrical Maintenance Safety Operation Program" "Electrical Operation Safety Operation Program"
VII. Deficiencies in the work and the next step of work In this year's work, I have achieved some work results through my own efforts. But I feel that there is still a big gap from a good technician standard. This is mainly manifested in, 1 in the sudden accident, some new equipment I am not particularly familiar with their performance, but also need to find information, affecting the timeliness of equipment troubleshooting; 2 the establishment of equipment files has not been carried out, mainly The completion data is not perfect, and the project is taking up a lot of energy. In this work, I feel a little helpless. 3 The training work has not been incorporated into the standardized system. Now, although the training work is carried out, due to lack of coordination, The effect of easy normal training is reduced; 4 The equipment standardization management work of the team is not caught, resulting in no further improvement in the work efficiency of the team.
In response to these shortcomings, I plan to continue to strengthen my learning efforts, to get through the new equipment as soon as possible, and to pass these new knowledge to employees as soon as possible, to improve the accuracy and efficiency of the company's overall electrical equipment troubleshooting. Improve the file establishment of electrical equipment of the whole company as soon as possible, synchronize paper documents and electronic documents, and improve the management level of the company's electrical equipment. Coordinate the relationship with other technicians, unify a unified training goal, incorporate training into the performance work of employees, establish an interactive platform between employees and technicians, and strive to create “help, learn, compare, catch, and super” the workshop. Such a dynamic collective. In addition, gradually standardize the equipment management of the team, and develop a standard model for each work, so that each work can be based on evidence, and improve the efficiency of the team on the basis of standardization.
